SPECIFICATION forming part of Letters Patent No. 445,197', dated January 27, 1891.

Application tiled September 9, 1890. Serial No. 364,449. (No model.)

To MZ whom t may concern:

Be it known that I, HENRY PHILLIPS, a citizen ot the United States, residing at Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Devices for Scouring Metallic Cylinders, fully described and represented in the following specification and the accompanying drawings, forming a part ot' the same.

The object ot this invention is to furnish an et't'ective means of applying a sand-blast to any point upon the periphery of a metallic cylinder to cleanse the same from scale or other impurities.

The invention consists in the combination, with the blast-pipe, of a hood having cheeks adapted to fit the cylindrical surface, in a particular construction for the blast-nozzle, and in the means for supporting and adjusting the metallic cylinder, and other details of construct-ion hereinafter described.

In the annexed drawings, Figure lis a front elevation of the apparatus. Fig. 2 is a plan of the same. Fig. 3 is an end view of the frame, with one of the cradles supporting a pipe. Fig. at is'a diagram showing a smaller cradle and pipe than that in Fig. 3. Fig. 5 is a section ot the machine online @c x in Fig. 2. Fig. ti is a view ot' the inner face of the hood. Fig. isa section of the same through the center, and l1`ig.8 is a diagram showing a loose cheek in contact with a pipe.

a are two parallel beams, provided with rails b, upon which the cradles for supporting the pipe are carried upon wheels c. Each cradle consists in an axle d, fitted loosely to a hole in the wheel c, and in a hanger c, provided with rollsf to support the pipe or cylinder g. The nozzle a is attached to a blastpipe 71, which is clamped upon one of the beams a by a strap A sandepipe s is shown connected with a branch s at the lower side ot' the nozzle n and hangs in a tank j, containing sand and water. The nozzle is provided with a hood having cheeks nl, and n1. fitted to the side of the pipe (j to prevent the mixture of sand and water ejected by the nozzle from splashing. The construction of the nozzle is shown in Fig. G, where the hood is shown clamped upon the nozzle by lock-nuts q. Steam or air may be used for the blast,

the blast-pipe 71. being connected with a passage o, opening into the rear of the nozzle, andthe sand-pipe s being connected with the passage o', which enters the interior of the nozzle obliquely at the end of the passage. As the nozzles are speedily worn out, they are preferably made ot' cast-iron, with the passages o o drilled therein. Such nozzle is readily iitted to receive thc lock-nu ts 1 and steam and sand pipes, and a new nozzle may thus at any time be applied to the hood at a tritling expense.

The hood consists of a back piece Z, endl plates l', and parallel flanges m', which are projected forward from the back piece at the top and bottom to touch the pipe above and below the point upon which the blast operates. The end plates Z are not designed to touch the pipe, but are constructed to clear the periphery of the smallest pipe to which the hood may be fitted, and the spaces at the opposite ends of the hood are closed by removable cheeks m, which are secured to the plates Z by thumb-screws i' or other suitable means. The pipeis in all cases placed in contact with the parallel checks m', and the curvature upon the'front edge of the loose cheeks m is made suitable to t such pipe, and to thus wholly close the hood at the ends.

In Fig. S a cheek is shown adapted to tit a smaller pipe and provided with holes r for the convenient application ot' the bolts vr. The cheek is shown in contact with a small pipe g of the same dimensionsas that shown in Fig. 4.

The checks ymy in Fig. 7 are formed with a suitable curve at their forward edges to t a pipe of the dimensions shown at g in Fig. 3.

The entire hood is preferably made of sheet metal to form a light construction, and the cheeks nl', at the top and bottom of the hood, may therefore be readily bcnt into contact with pipes of various diameters.

The cradles shown in Fig. S are peculiarly adapted to present any point upon thc sur face of the pipe g/ to thc blast, as the rollsf permit the pipe to be rotated easily upon its own axis, while the axles (t are arranged to slip through the wheels c, so as to move the pipe to and from the hood, so as to inspect the portion operated upon. As the wheels lOO simply rest upon the rails Z), the cradles may be readily removed and replaced by others of larger or smaller size, and a pipe of any required size may thus be supported with its central line upon a level with the nozzle, like the pipe gin Fig. 4.

[n Fig. 8 a cradle is shown for a smaller pipe, and the saine cradle can be used for different-sized pipes by substituting larger or smaller rolls for the rolls It is not essential that a mixture of sand and water should be used in practicing this invention, as dry sand may be used, if preferred; but the wet sand is preferable in such an operation,as it is desired to frequently remove the pipe from the hood to inspect the operation of the blast, in which case the dry sand would be dispersed a great deal more than the mixture ot' sand and water.

It is found in practice that the sand escapes somewhat at the lower edge of the hood, where its gravity causes it to accumulate and the blast expels it, and a guard p is therefore provided upon the opposite side of the pipe g and extended down to the tank j to con.- duct the sand and water thereto. Such guard is indicated partly in dotted lines in Figs. l and 2 as Well as in Fig. 7. By the construction shown the pipe is movable freely in every direction, so that it may be readily shifted to present anypoint upon its surface to the blast.

It will be understood that any number of the cradles maybe applied beneath a pipe or metal cylinder and arranged at any distance apart, and it will be readily seen that the wheels c furnish a means of shifting the pipe longitudinally,while the loose axles d' permit its movement transversely to the frame a, and the rollersf sustain it movably upon its own axis.

\Vith this apparatus bars or pipes of considerable Weight may be easily shifted into the desired relation tothe blast and the scale rapidly removed from the exterior of the same,

so as to permit the tinning, galvanizing, or

copper-ing of the same locally. Metallic'pipes may thus be prepared forbrazing, for soldering on branches, or for any other treatment requiring` a bright clean surface.

Having thus set forth the nature of the invention, what is claimed herein isl. In a device for scouring metallic cylinders, the combination, with a blast-nozzle oz, supplied with jet-pipe 71, and sand-pipe s, of a hood provided with the cheeks fitted, respectively, to the straight and curved sides of the cylinder, substantially as herein set forth.

2. In a device for scouring metallic cylinders, the combination, with a blast-nozzle n, supplied With j et-pipe h and sand-pipe s, of a hood provided with the flexible sheet-metal cheeks m and removable cheeks m, as and for the purpose set forth.

3. In a device for scouring metallic cylinders, the combination, with the blast-nozzle n, provided with the passages 0 and o', arranged as described, of the jam-nuts q, fitted to the end of the nozzle, the hood Z, clamped between the jam-nuts, the iiexible cheeks m at the top and bottom of the hood and the removable cheeks on at the ends of the hood, and bolts r for securing such removable cheeks, as and for the purpose set forth.

4. The apparatus herein described for scouring metallic cylinders, consisting in the frame carrying the rails b, cradles having axles iitted to Wheels upon such rails and adapted to sustain a cylinder movable in relation to the frame, and the nozzle n1, sustained upon the frame with the hood Z attached thereto and provided with cheeks m to fit the side of the cylinder, substantially as herein set forth.

5. The apparatusherein described for scouring metallic cylinders, consisting in the frame carrying the rails b, the wheels c, the cradle e, with axles d, tted loosely to the wheels and provided with the anti-friction rolls f, and a nozzle n, sustained upon the frame with the hood attached thereto and provided with cheeks m to tit the sides of the cylinder, substantially as herein setforth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

Y HENRY PHILLIPS.
